Jade be very careful with planting mint. It will go all over the place. I had liquorish mint that was given to me as Black Basil but was really in the mint family as it had the square stems. The plant was beautiful and I loved using it's color to mix in with my flower gardens. When it flowered I let it go to seed and the wind spread those seeds all over my garden and lawn. I had millions of plants that I battled for years. I say if you want mint for your tea find a vacant lot in your area and spread the seeds there and when you want a cup of tea take awalk and pick some. lol
peppermint is my favorite by far ....yesterday I was given a mint...or at least I think it is a mint called...Yerba Buena....Spanish for "good herb....from what I was told it is a pain reliever ...I need to do more research....I do remember as a child my granny growing something the same if not this plant..
When you find out what it actually is let me know. A natural pain reliever is always good in the garden. I have a poor old dog ( actually 2 brother & sister) who are on rimadyl and it is way expensive. They will eat /drink anything I tell them to so that might be a better pain reiliver for them with less side effects.
